As i sayed in previous post :
Write a sample/testcase, with your third dll who show the "crash",
make an archive of evrything then post a bugreport at bugzilla whit
your testcase + description include :
https://bugzilla.novell.com/index.cgi

After you need to wait, or/and try to geed more feedback on IRC chanel #mono

Cordially.

Small Eric Quotations of the days:
---------------------------------------------------------------------------
If one day one reproaches you that your work is not a work of
professional, say you that:
Amateurs built the arch of Noah, and professionals the Titanic.
---------------------------------------------------------------------------

Few people are done for independence, it is the privilege of the powerful ones.
---------------------------------------------------------------------------
